+CASE:A 25 year old is brought to casualty with history of fall from a height of 20 feet. He landed on a pile of bricks. Fortunately there was no head injury. He is complaining of severe abdominal pain. On examination he is conscious; his pulse is 110/minute, BP 90/60 mmHg. There is no external wound. However has abrasions in left upper quadrant and left lower chest.

+MECHANISMS OF TRAUMA Trauma can be classified in type by causation and by effectBlunt , e.g. car bonnetPenetrating , e.g. KnifeBlast , e.g. BombCrush , e.g. building collapseThermal

+Deaths from trauma show three peaks:
Immediate death :
o Occurs within secondso Cause : head injury , heart injury or aortic injuryo These deaths are not preventable
![Page 5: Trauma](https://reader030.vdocuments.mx/reader030/viewer/2022020723/54859f9eb4af9f5b7b8b483b/html5/thumbnails/5.jpg)
+
Early death:
o Begins an hour or two after injuryo Cause: subdural and epidural hematomas , hemo or
pneumothorax , organ rupture or blood losso Often preventableo This period is called the GOLDEN HOUR during which
prompt intervention can save a life

+
Late death:
o Occurs many days after injuryo Cause: sepsis or multi-organ failureo Prompt treatment of shock and hypoxemia during
GOLDEN HOUR can reduce these deaths

STEPS IN ADVANCED TRAUMA LIFE SUPPORT: Prehospital care Primary survey with simultaneous resuscitation: identify and treat what is killing the patient Secondary survey : proceed to identify all other injuries Definitive care: develop a definitive management plan

PREHOSPITAL CARE

+Prior to arrival: Ensure senior emergency medical and nursing staff are aware of
all available details of the case. Call Trauma Team (Trauma surgeon , Anaesthetist , Nurses ,
Emergency physician , Respiratory therapist , Radiologist , Surgical subspecialists)
Delegate specific tasks to appropriate individuals. Check the resuscitation equipment and prepare intravenous lines
and fluids. If possible, estimate the patient's weight using the formula (Age
+ 4) x 2 (or 3 x Age for those over 9 years) and calculate:
1) The amount of fluid bolus at 20 ml/kg
2)The endotracheal tube size (age/ 4) + 4
3)Any other drugs likely to be needed
![Page 11: Trauma](https://reader030.vdocuments.mx/reader030/viewer/2022020723/54859f9eb4af9f5b7b8b483b/html5/thumbnails/11.jpg)
+On arrival:
Immediately perform a primary survey by assessing and managing the patient's airway, with cervical spine stabilisation, breathing and circulation.
Obtain a history, if possible, from the attendents or ambulance officers e.g. type of trauma, speed of the vehicle, height of the fall, restraints or safety equipment used, whether other people were injured.
Obtain information regarding any treatment or interventions to date.

+Identified the life-threatening conditions and simultaneously manage:
A: Airway maintenance with cervical spine protection
B: Breathing and ventilation
C: Circulation with hemorrhage control
D: Disability ( Neurologic status )
E: Exposure / Environmental control: Undress the patient & prevent hypothermia
![Page 14: Trauma](https://reader030.vdocuments.mx/reader030/viewer/2022020723/54859f9eb4af9f5b7b8b483b/html5/thumbnails/14.jpg)
+A : Airway and C- spine
A patient who can speak clearly must have a clear airway
Unconscious patient may require airway and ventilatory assistance.
The cervical spine must be protected during endotracheal intubation if a head, neck or chest injury is suspected.
Airway obstruction is most commonly due to obstruction by the tongue in the unconscious patient.
Hoarsness or pain with speaking indicate
laryngeal injury.
* Talk to the patient
![Page 15: Trauma](https://reader030.vdocuments.mx/reader030/viewer/2022020723/54859f9eb4af9f5b7b8b483b/html5/thumbnails/15.jpg)
+
The signs of airway obstruction may include: snoring or gurgling ( foreign body , aspiration
) stridor or abnormal breath sounds agitation (hypoxia) using the accessory muscles of
ventilation/paradoxical chest movements cyanosis.
* Assess airway
![Page 16: Trauma](https://reader030.vdocuments.mx/reader030/viewer/2022020723/54859f9eb4af9f5b7b8b483b/html5/thumbnails/16.jpg)
+
Indications for advanced airway management techniques for securing the airway include:
o persisting airway obstructiono penetrating neck trauma with haematoma (expanding)o Apnoeao Hypoxiao severe head injuryo chest traumao maxillofacial injury
* Consider need for advanced airway management
![Page 17: Trauma](https://reader030.vdocuments.mx/reader030/viewer/2022020723/54859f9eb4af9f5b7b8b483b/html5/thumbnails/17.jpg)
+
Advanced airway management: * * If obstruction persists: - Chin lift and Jaw thrust - Consider C-spine injury in every patient until proven otherwise
•Endotracheal intubation if:- above don’t help - unconscious patient - airway swelling or burns -GCS less than 8
* Surgical Cricothyrotomy (if there is severe facial or neck injury)
